A new Vancouver office building known as oN5 was quickly constructed with entirely insulated, prefabricated cross-laminated timber (CLT)

The HTFS combines cross-laminated timber panels with steel and concrete to build high-rise towers with a reduced carbon footprint.

The construction industry has witnessed an ongoing trend toward large-dimension material panels over the last 60 to 70 years. A pattern of 1.2 x 2.4-m (4 x 8-ft) sheets of oriented strandboard (OSB) and plywood have replaced 0.3 x 3- or 0.3 x 3.6-m (1 x 10- or 1 x 12-ft) shiplap board stock as the sheathing material of choice.

In London, Ont., a multi-residential apartment building built in 1970 was beginning to show significant signs of wear and tear on its exterior clay through-the-wall (TTW) brick, and owners had to develop a plan. Having already undertaken smaller localized repairs in the past, new water penetration issues on the upper, west-facing floors where the building is susceptible to driving rains, were cause to go in another direction.

Driven by the principles of high-performance energy (HPE) buildings through government, energy codes, and the green building movement, building energy designs across Canada and around the world strive to improve. The increasing focus on the implementation of energy-efficiency requirements, for both new construction and deep energy retrofits for commercial and public buildings, begins with envelope-first energy efficiency, reduced energy demand loads, and related greenhouse gas (GHG) reductions.
